Definitions
- This invention relates to the diamond segments and inserts used as tools of disks, milling cutters and saws for the cutting and the polishing of granites, stones, marbles, concrete, asphalt and analogous hard materials.
- these tools must have various requisites, among which such mechanico-structural characteristics as to enable obtaining perfectly linear cuts without chippings on the edges of the material to be cut.
- the cutting is useful for the cutting to be carried out quickly in order to ensure the smallest possible consumption of current during the work and to enable reducing the operating costs whereas the tool should be worn out uniformly along the cutting surface in order to have a satisfactorily long life.
- the tool has also to aid in reducing as much as possible the noise during the cutting and, in some cases, it should also enable to obtain a good surface polishing of the cut material.
- the object of the invention is to provide a tool which will possess all the characteristics mentioned above and at the same time will be low cost of production, contrarily to other tools existing on the market which are very expensive and enable to obtain only some of the advantages mentioned hereinabove.
- the so-called sandwich segments formed by an inner layer of soft material enclosed between outer layers of a more resisting material or between two outer layers having a higher concentration of diamonds as compared with that of the inner layer.
- This tool very expensive to manufacture in both cases, enables to obtain an even surface wear of the tool without rounding off the edges, but does not possess any of the characteristics mentioned above.
- the invention provides a diamond segment or insert for the cutting of hard materials, characterized in being provided on one of its main surfaces with dead holes which are shaped and distributed in such a manner that all the cross-sections perpendicular to the longitudinal axis of the tool originate full surfaces whose areas are all of them substantially equal to each other and in a constant ratio with the rated cross-section of the tool, whatever the degree of wear of the tool may be.
- FIG. 1 is a front view of the tool according to the invention in a preferred embodiment thereof;
- FIGS. 2 and 3 are cross-sections along lines II--II and III--III of FIG. 1.;
- FIG. 4 is a partial view of a disk carrying the tools according to the invention.
- FIG. 5 is a partial view of the disk of FIG. 4 in the direction of the arrow A;
- the represented distribution of the holes 11 ensures that during the work, and accordingly during the wear of the tool, this latter will always keep such a structure that the surfaces S of its vertical cross-sections, though being reduced, will remain substantially equal to each other till the complete wear of the tool.
- the openings 11 which always appear on the cutting surface of the tool (see FIG. 5) permit a high cutting speed thanks to the reduction of the metal friction surface as compared with a solid tool, and hence a smaller consumption of current, the material to be cut being equal.
- the global cutting surface formed by the sum of the cutting surfaces of all the tools has an intermediate linear portion having the width 2(p-s/2) which extends from the two sides of the center line x of the cutting surface, whose area is smaller than that of the two portions s-P which lie laterally with respect to it.
